Corrected entry: The show takes place in 1960 and a calendar shows it to be March. At one point, Don Draper chews out Pete Campbell for stealing a discarded health report regarding cigarettes. Don tells him that there is nothing out there that will magically make copies of something (eluding that photocopiers hadn't been invented yet). In 1959, Xerox introduced the Xerox 914, the world's first plain paper photocopier. By the end of 1961, the 914 had generated almost $60 million in revenue. The series takes place in the biggest and best ad agency of New York City. If they didn't own one, surely they would know about the ad campaign surrounding it.

Correction:In that episode Don was being sarcastic when he said that. He was making the point that he has the same info that Pete does, and if he thought it was useful he would have used it to begin with.

When Christina Hendricks is about to leave the office, while talking to Don, she is wearing a scarf on her hair. The scarf corner is alternatively tucked in her coat collar and then outside, and inside again etc. in alternate angle shots of the scene.

The character Ted Chaough is briefly heard ordering an "Old Spanish" at a bar during the episode. This is a very quick and subtle reference to the popular cult-comedy series "30 Rock." In "30 Rock", the "Old Spanish" is a fake drink that character Cooter Burger is jokingly convinced is real as a prank by co-workers at the White House. The drink was rather nauseatingly comprised of red wine, tonic water and olives. "Mad Men" star Jon Hamm had previously co-starred on "30 Rock" and is friendly with its creator Tina Fey, thus the reference.
